I remember according to the plot, all the men were infected with zombies except the main character so he got zombie antibodies but why are there men in the underground and Lucy's plot developer

they probably immune too but I hope there is a meta joke where they only want the mc

Something would probably happen in the underground city where all the men turned

but in news, this reporter said there are districts where zombies won't appear, so maybe undergrounds is one of these districts? Zombies appear on Colosseum 'cos Reevs bring them there.
